Hard to believe me saying this, but Lawrence is right on the money. Chem Lawn does charge that and what he said about the rental is correct too. Try to figure what it would cost them with their time, money and the hassle of picking up such a sizeable machine in their Bimmers and Suv's. Not to mention the little white collar guys manuvering this machine would be worth watching. Once they see what this process entails, they shouldn't cry too much.
